Firearm Overhaul v0.1 by Asdow file - Dead Island

Introduction by the developer, Asdow:

Version 0.1

Firearms' damage, accuracy, recoil, reload speed, spare ammo and ironsights tweaked to behave more realistically based on my own limited experience with firearms.

Pistols and revolvers are now accurate to 30 meters or so to a stationary target, shotguns up to 50-70 meters, and rifles to 100-150 meters.

Ideally, rifles would be accurate to such lengths only by crouching, but so far I haven't found a setting how to implement that.

Infected and humans drop from 1-3 torso hits, walkers are killed only from headshots, except with melee weapons because of the "cut both arms and kick the zombie down insta-kill" issue.

Works best in the city with zombiedensitymod set to 45 or more. Haven't gotten to the jungle yet so I can't say if the game works there with the increased zombie density.
If playing act1 and the game crashes, remove the ai_props.scr

Gun damage values, recoil and reload speeds can be tweaked from the default_levels.xml

Any modders finding something useful from these, feel free to tweak/include them in your own mods.

There is two versions in the .zip file, FULL and LITE.
LITE has only the guns' changes, melee durability changes, a little tweaked humans and enhanced AI zombies and infected from Dead Island plus mod.

FULL has gun changes, HUD changes, headshot only killable walkers, increased zombie amount, increased death penalty, melee weapon durability changes, stackable energy drinks, snacks and fruits from Dead Island plus and hopefully slowed down leveling by increased experience requirements. Not sure whether the last one works.
